DEVICE FOR POINTING WOODEN PENC'ILS.

Application filed March 28, 1925. Serial No. 18,934.

` The devices hitherto used for pointing and sharpening wooden pencilsby hand, such as knives. pencil pointers, pencil files, etc.. have thedisadvantage that t-he shavmgs fall down and either remain in the roomand litter up the floor, or must be collected in a special receptacle ofcomparatively large size such as a waste-paper basket; further theshavings soil the hands, clothes, drawings etc., and the air of the roombecomes filled with graphite dust.

The object of invention is to eliminate these drawbacks, since thesharpening or pointing tool is completely enclosed and iiXed in a boxwhich receives the shavings and is provided with al removable cover. IThe drawing shows some practical embodiments of the invention. Fig. l isa longitudinal section on the line 1-1 of Fig. 3 looking in thedirection of the arrows of a pencil pointer in combination with a pencilfile,4 and Fig. 2 alongitudinal section of a pencil file, of modifiedform, while Fig. 3 is a cross section of the device as shown in Fig. 2,on the line 3-3 of Fig. l, looking in the direction of the arrows.

In Figs. 1 and 3 a is a casing which may be made out of any suitablematerial such as 'transparent celluloid. This casing is tubular and isclosed at one end by a cap 7a and at t-he other end by a cap 7c. Insideof this casing is an ordinary pencil cutter m which has a conical boretherein opening through one end to receive the point of the pencil. Thisbore opens also through one side of the cutter by means of alongitudinal slot and to the outside of the cutter will be fixed a bladea, having a sharp edge adjacent said slot. This type of cutter is wellknown and to sharpen a pencil, the pencil indicated at L in broken linesin Fig. l is pushed' into the open end of this cutter and turned so thatthe end is shaved by the blade n. This cutter is mounted in the cap f bybeing passed througha central hole into the casing and it has a flange19 at its outer end to engage the exterior sur-v face of the cap f. 4

' The inner end of the cutter n has a threaded projection g which screwsinto a threaded opening in the Sharpener file Z) which has several facesso that the point of a pencil can be rubbed over one of these faces tomake the point as fine as desired. A slot e in the sideA of the casingadmits the pencil. The cap 7c at the other end of the casing has anopening for a rod or bolt c, which screws into a threaded opening in theother end of the file `b. This bolt is surrounded by a handle g whichhas a central bore for the bolt. The

outer end of this bore may bc enlarged and terminate in an insideshoulder s, and between the head of the bolt and the shoulder is aspring Z encirclingthis bolt c. The head of the bolt c should be withinthe handle g and the spring acts to force the bolt outward so as topull` upon the file and sharpener n and hold the flange p against theoutside of the collar The casing a may have a base i". Tn `F 2 thesharpener omitted and the file h is engaged by ai'od or bolt o passing70 through the cap f and encircled by a spring el. Between the head of'the bolt shown at z" and the outside of the casing a is the washer fwpressed by the spring CZ against the cap 7.

The other end of the lilo may have a shank or bolt o passing through thecap c and made fast to a handle g. In this form the point of the pencilis rubbed on the sharpener file Y) by inserting it in the slot e in thecasing a,

and the file can be turned to bring any one of its faces into positionfor operation by means of the handle g.

The handle g may also serve in the device of Fig. l to turn the file andit may be fixed to the bolt c for this purpose. Also the file 7) in Fig.l might be turned by a tool engaging the head of the bolt e.

To open the box and empty the shavings or bits 4of dust from the pointof the pencil7 the cover j can be taken off against the pressure of thespring cl. in Fig. 2 the cover f may be pulled over against the pressureof the spring d and the head z' may be a nut which can be turned to varythe pressure of the spring CZ. In Fig. 2 the user may take 95 hold ofthe handle g and turn the casing a to bring the slot e in line with anyof the faces of the file ZJ.

What I claim is l. A pencil Sharpener comprising a casing, having a slotin one wall thereof, a movable rod extending through the end of thecasing and outwardly spring held, a Sharpener attached to the rod withinthe casing, and having several working faces so that the sharpener canbe actuated to bring any of its faces in position and held to act upon apencil inserted through the slot in the casing.

2. A pencil sharpener comprising a casing, having a slot in one wall, ahandle carried by the end of the casing, a movable rod extending throughthe handle into the casing and outwardlyspring held, a Sharpener havingseveral Working faces, attached to the rod Within the casing and adaptedto be actuated to bring any of its vfaces in position and then throughthe handle and outwardly springA held, asharpener carried adjacent theinner end of the rod within the casing having al series Yof workinglfaces, land adapted to be j turned so that any of the Working faces ofthe Sharpener can be brought into position and then held by the rod toact upon a pencil inserted through the slot, and means including a.flange engaging the other end of the casing and*v projecting into thecasing and united to the Sharpener at the end remote from said rod.- i f4. A pencil Sharpener comprising acasing having a slot inone wall,a-handle carried by the end of the casing, a movable rod extendingthrough-the handle into the casing, a [ile carried by the rod within thecasing a'ving a series of Working faces adapted to be turned to Y bringany of its faces in a osition to act upon a pencil inserted through t 1eslot.

5. A pencil sharpener comprising a casing having a longitudinal openingin one Wall, a Sharpener rotatably mounted in the casin and having aseries of sharpening faces an means for rotating said Sharpener so thatany one of its working faces may be brought into position to act upon apencil inserted through the opening in the casing.

(i. A pensi] Sharpener comprising a casing having a slot in one wallthereof, a Shar ener rotatably mounted in the casing and a justablyspring held, and having a series of sharpening `faces, whereby it may berotated so that any of its faces can be brought into a position to actupon the point of a pencil inserted through the slot.

In testimony whereof I have signed my name to this specification.
